SHAFT-ALINER.

Specification of Letters Patent.

Patented Bed. 1.2, 1905.

To all whom it may concern:

Be it known that I, HARLAN L. NEWTON, ofSandycreek, in the county ofOswego, in the State of New York, have invented new and usefulImprovements in Shaft-Aliners, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to improvements in shaft-aliners in which twoopposed rectangular jaws are slidably interlocked with each other toreceive and center themselves upon the shaft to be alined, one of thejaws having a laterally-extending arm equipped with a level and plumb,the former to bring the arm to the same level when the aws are appliedto different parts of the shaft and the plumb cooperating with astraight line or cord by which the vertical and horizontal alinementsof. the shaft are determined. Therimary object is to provide a simpleand e cient instrument by which a shaft of any length may be adjusted atany point or points to the same relative position with reference to apreviously-prepared straight line or cord.

Another object is to render the work of alining the shaft as easy andexpeditious as possible bysuspending the jaws upon the sectional viewtaken on line 2 2, Fig. 1.

shaft in such manner that the horizontal arm will be automaticallybrought toward a level .by the mere gravity of the pendent arms withwhich the jaws are provided, so that when the lever is applied only aslight adjustment, if any, is required to bring the horizontal arm to anexact level position, whereupon the jaws are rigidly clamped upon theshaft. A more specific object is to enable the instrument to be used inconnectionwith a tightly-drawn cord or line placed close to thefloor-line of the room in which the shaft is located, therebyfacilitating the arrangement of the cord or line in both horizontal andvertical planes parallel to the axis in which it is desired to locatethe shaft.

, Other more specific objects and uses will be brought out in thefollowing description.

I In the drawings, Figure 1 is a side elevation of my improved alininginstrument shown as operatively mounted upon a shaft and as associatedwith the line or cord with which the shaft is to be alined. Fig. 2 is aFigs.

3, 4, and 5 are sectional views taken, respectively, on lines 3 3, 4 4,and 5 5, Fig. 1.

As best seen in Fig. 1, this alining instrument consists, essentially,of a pair of rectangular open-sided jaws 1 and 2, each having a pendentarm 3 and 4, which are provided with transverse apertures in planes oneabove the other for receiving guide-rods 5 and 6, the jaw 2 beingprovided with a laterally-projecting substantially horizontal arm 7,upon which is supported a slidable level 8 and a sliding gage 9, thelatter receiving and supporting a pendent plumb 10, adapted to registerwith an alining cord orline 11.

The arms of the jaw 2 are bifurcated for forming open-ended slots 12 toreceive the adjacent arms of the jaw 1, said latter arms being reducedin width to fit and slide in the slots 12, thereby interlocking one jawwith the other and permitting said jaws to be brought close together oradjusted radially with reference to the shaft to fit and centerthemselves upon any shaft within certain limits of size or diameter.Thesejaws are simultaneously applied to o posite faces of the shaftwhich is to be aline and the pendent' arms 3 and 4 are of sufficientweight to substantially counterbalance. each other and topartially,counterbalance the weight of the arm 7, so that when theinstrument is thus applied to the shaft before the plumb 10 is attachedthe arm 7 is brought toward a substantially horizontal or levelposition.

The rods 5 and 6 are arranged in parallel.

lines horizontally one above the other parallel with the rod 7 and areboth threaded at one end, the threaded end of the rod 6 being screwedinto a threaded aperture 13 in the pendent arm 4, and its other endextends through a smooth bore in the pendent arm 3.

The guide-rod 5 is passed entirely through smooth apertures in both ofthe pendent arms 3 and 4, and its threaded end is provided with a nut 14for a purpose presently tion, so that the operator may with one handengage the arm 7 and bringit to an exact level position, as indicated bythe level 8, while with the other hand he may readily tighten thethumb-nut 14 to more firmly clamp the jaws 1 and 2 upon the shaft.Previous to this operation, and, in fact, the first step in the processof alining the shaft, the cord or line 11 is secured in a direct lineparallel with that in which the shaft is to be alined, so that when thejaws 1 and 2 are clamped upon one part of the shaft and the arm 7brought to a level the age 9 is then adjusted along the arm 7 unti thepoint of the plumb 10 registers exactly with the point in the cord 11 atright angles to the shaft.

The 'bar 7 is provided with suitable graduations 16, along which thegage 9 is movable to determine the exact horizontal distance of thecenter of the shaft A from the vertical plane of the alining cord 11,and when the shaft has been brought to the desired position at one pointthe clamping-jaws 1 and 2 may be loosened and moved along the shaft toanother point and then reolamped and leveled up in the manner previouslydescribed, care being taken to previously clamp the gage 9 in theprevious position by means of a thumb-screw 17, so that when theposition of the clamping-jaws is changed from one place to another uponthe shaft the position of the point of the plumb 10 with ref erence tothe line or cord 11 will quickly de termine whether or not this part ofthe shaft being tested is in alinement, and if not just how much it isout of alinement will be indi cated by the gage 9, whereupon the part ofthe shaft now being alined is adjusted until the point of the plumbcomes into direct registration with the cord or line 11.

It is now clearly evident that by making the plumb-sustaining cord, as18, of pianowire or similar material, and at the same time bringing thecord 11 to a level position the shaft A may be simultaneously alined inboth a horizontal and a vertical position. In other words, it may bebrought to an exact level or parallel with the horizontal and verticalplanes of the level cord 11.

I have clearly shown how the horizontal adjustment of the shaft iseffected, and it is as clearly obvious that the vertical adjustment ofsaid shaft may be effected through the medium of a plumb and itssustaining-wire 18 by allowing the point of the plumb to just touch thecord 11 as the jaws are moved to different positions along the shaft andthe arm 7 brought to a level or horizontal position, as indicated by thelevel 8.

As shown in Fig. 1, the arm 7 is made in sections of convenient length,divided at 20, and their meeting ends provided with a threaded socketand screw, respectively, for attachment one to the other, the sectionadjacent to the jaw 2 having a threaded end which is screwed into athreaded socket in said jaw, thereby permitting the arm 7 to bedetached, and the rods 5 and 6 are also detachable from the arms 3 and4, so that all the parts may be separated and arranged lengthwise onewith the other for convenience in storage, boxing, or transportation. Itwill also be observed upon reference to Figs. 1 and 2 that the level 8is provided with a pair of hooks 21, which hook upon the rod 7 and notonly have a sliding movement lengthwise of said rod, but permit thelevel to swing thereon, and thereby automatically adjust itself in theform of a pendant below the rod.

What I claim is 1. A shaft-alining device, comprising two open-sidedjaws having their open sides facing and interlocked with each other, alaterally-projecting rod on one of the jaws, a level slidable upon saidrod and means for clamping said aws upon a shaft.

2.

3. In a shaft-alining device, the combination of two opposed jaws andmeans for drawin them together to engage opposite faces 0 the shaft, anarm projecting laterally from one of the jaws, a level on said arm forbringing the latter to a level, a gage adjustable on the arm, and aplumb suspended from said gage.

4. In a shaft-alining device, two opposed jaws and means for drawingthem together to engage opposite faces of the shaft, one of the jawsbeing provided with a laterally-proj ecting arm, a gage slidable lenthwise on the arm and a plumb sus ended om the gage for the purposedescri ed.

5. In a shaft-alining device, two opposed jaws having pendent arms,guide rods mounted upon one of the pendent arms and upon which the otherpendent arm is movable, a horizontal bar secured to one of the jaws anda plumb adjustably supported upon said bar.
